Since there is no built-in way to align numeric columns to a decimal

point,17 we can “cheat” and do it by using two columns: a right-aligned inte￾ger and a left-aligned fraction. The @{.} command in the \begin{tabular}

line replaces the normal inter-column spacing with just a “.”, giving the ap￾pearance of a single, decimal-point-justified column. Don’t forget to replace

the decimal point in your numbers with a column separator (&)! A column

label can be placed above our numeric “column” by using the \multicolumn

command.

Material typeset with the tabular environment always stays together on

one page. If you want to typeset long tables, you might want to use the

longtable environments.
